Application June s, 193s, seriai No. 212,590 In New Zealand October 15, 1937 3 Claims.

The invention relates to stays for doors of automobiles` and the like, which are used in such positions that said doors when released from the fastenings usually fitted tol keep them closed, are unable to remain in a desired position owing to the inclination or slope of the door mountings which is responsible for said doors swinging either to the fully open, or the fully closed postion according to the inclination or `slopeof the door mounting.

The object of the invention is to provide for use between a pllaror the like from which a door is hung and said door, an improved form of stay capable of being adjusted and set to hold the door in a desired position.

rI'he improved stay provided by the invention comprises a rod pivotally attached at one end to the xture from which the door is hung; a plate mounted to travel on the door and having the other end of said rod pivotally connected therewith, and means for regulating travel of said plate.

In the accompanying drawing, in conjunction with which the inventiony will` be more particularly described- Figure 1 is a part elevation showing the improved stay iitted to a door and adjusted to hold the latter in a partly open position.

Figure 2 an elevation of the parts appearing in Figure l, but showing the stay in the position it occupies when the door is closed,

Figure 3 a sectional plan view of the plates which are mounted on the door,

Figure 4 a detail view illustrating an alterna- 35 tive way of connecting the rod of the stay with the plate adapted to travel on the door, and

Figures 5 and 6 part elevations illustrating different positions of the travelling plate when same is pivotally mounted.

The stay comprises a rod I pivoted at one end between lugs 2 on a plate 3 secured to a fixture, such as the pillar 4, from which the door 5 is hung in usual manner, said lugs 2 projecting from the face of the pillar yI4 against which the door closes, an opening 6 in the door enabling the latter to pass upon the lugs 2 and also accommodating the rod I.

Atits other end the rod I is connected to the outer end of a plate 1 mounted to travel between the doubled vportions of a plate 8 secured through one of said portions to the inside of the lining or inner surface of the door 5, the outer end ofthe plate 1 being oiset to lie in the same plane as the portion of the doubled plate 8 removed or distant from the lining or inner surface of the door.

As `shown in Figures 1 and 2, the plateV 1 is slidable in the Adoubled plate 8, a screw pin 9 which is passed through a plain hole I6 in the portion of the plate 8 secured to the door 5 and is entered in a screw threaded hole I1 in the other or inner portion of the plate 8 also passing through a slot 1a in the plate 'I and having on its end located at the inner side of the door 5, a ilange I`8 and a handle I0 by means of which the screw pin 9 can be turned to draw the two portions of the doubled plate 8 together and so clamp orgrip between them the plate 'I to prel vent movement thereof.

When` the door 5 is fully closed, the stay occupiesthe position illustrated in FigureZlwith the plate 1 pushed right in between the doubled portions of the plate 8, and as said door is opened, the rod I, owing to its being attached to the pillar 4, causes the plate 1 to be drawn outwards between the doubled portions of the plate 8 according to how far the door is opened, and the latter may be retained in any desired open position by turning the screw pin 9 to cause the plate 1 to be gripped between the doubled portions of the plate 8.

The rod I can be provided with a fork II, and be pivoted as at I2 to the plate 1, or the latter can have fitted thereto a socket I3 to take a ball I4 on the end of the rod I, so that a ball and socket joint is providedvbetween the rod I and the plate 1.

Also the hole Ia in the rod I at its end attached to the pillar 4, is made somewhat larger than the pivot pin passed therethrough, and the space between the lugs 2 is made sulicient to permit the end of the rod I to rock on the pivot pin between the lugs 2 and similarly the holes in the fork II are made larger than the pvot pin I2 and increase in diameter outwards while sucient space is left between the legs of the fork I I to permit the latter to rock on the pin I2.

The play or rocking allowed in the joints just described, is provided to overcome slight misalignment of or inaccuracies in tting the various parts, the ball and socket joint, when used, also assisting in overcoming misalignment or inaccuracies.

instead of the plate 1 sliding in the doubled plate 8, it can be pivoted therein by the screw pin 9, the rod I being connected to the lower 01T- set portion of the plate 'I' which as the door 5 is opened and closed, swings on the pin 9, said plate 1 being locked as before by being gripped between the two portions of the doubled plate 8.

Pivotal movement of the plate l about the screw pin 9 in both directions is limited by a stop I on said plate 'l engaging the lower edge of the portion of the doubled plate 8 secured to the door 5, the lower edge of said plate portion being cut away as shown to permit the requisite movement of the plate 1.

The doubled plate 8 can be compressed to grip the plate 1 and hold the door 5 against movement on its hinges, or it can be set to act as a check or brake on opening and closing movement of the door, or it can be released to allow the door 5 to swing on its hinges without hindrance, and be compressed only when required to retain the door 5 in a desired open position.

When the sliding plate 1 is used, the slot 'la ln the latter works on a guide pin 8a on the plate 8, said pin 8a and the screw pin 9 maintaining the plate 'I in the correct position for operation.

What I do claim and desire to obtain by Letters Patientpof the United States of America is:

1. A stay for hinged doors, comprising a bracket attached to the xture from which the door is hung, a rod pivotally connected at one end to the bracket and arranged through an opening in the inner edge of the door, a plate doubled upon itself and secured within the door; another plate having a slot therein mounted to slide between the portions of the doubledplate and having an offset portion at the outer end thereof operably connected to the other end of the rod; a anged screw pin passed through said doubled plate and the slotted plate to provide means for compressing said doubled plate on the slotted plate, and a handle on said screw pin.

2. A stay for hinged doors, comprising a. bracket attached to the xture from which the door is hung, a rod pivotally connected at one end to the bracket and arranged through an opening in the inner edge of the door; a plate doubled upon itself and secured within the door; another plate pivotally mounted at one end between the portions of the doubled plate, and

vhaving an offset portion at the outer end thereof and operably connected to the other end of the rod; a flanged screw pin passed through said doubled plate and the plate therein, to provide the pivot for the latter, and also means for compressing the doubled plate on the plate therein; a handle on said screw pin and a stop on the pivoted plate adapted to engage the doubled plate.

3. A check for holding an auto door in the desired position relative to a door post including a bracket on the post, the door having an aperture provided on its inner end adjacent the door post and adapted to receive the bracket, a plate member bent upon itself and secured within the door, a second plate member movably mounted between the bent portions of the plate member and provided with an oiTset portion at one end thereof, manually operable means on the door for releasably clamping said second plate member in any desired position between the bent portion of the said rst mentioned plate member, and a connecting rod operatively connected at one end to the oiset portion of the said second mentioned plate member and at the other end to the bracket on the door post.
